You were right though, I did finally make it into Diamond III today.
Congrats! Next season, if you can move one further up again, and then the one after - then you will start in diamond :)
Do you get rewards from both sides?
Yes, but the rewards are calculated on last season, and the cost of buying energy is on the highest side. So for instance, if I am in Champion Modern where the cost of energy is 500, the cost of energy in Bronze Wild would still be 500. This is to stop buying "cheap energy" and using it on a higher league.
The daily quest rewards are combined too - so if getting Champion rewards, playing bronze in the other side is going to be very slow progress. But, if playing both the same like Diamond on each side, both add to the quest.
The SPS rewards are quite different though. There is more to be earned in Modern I think, because there are no/less bots. Wild is filled with maximizers.
Interesting. Thanks for the info. I think I understand it. I'm actually surprised I have done so well given that these are just my GF cards. Most of my regular foil cards are being rented out.
